What are the functions of suspended rubber shock absorber
Ordinary people hear of suspension spring shock absorbers, but few people hear of suspension rubber shock absorbers. In fact, many people classify both as the former, so few people hear of suspension rubber shock absorbers. However, both of them have different functions. Like other rubber shock absorbers, the suspended rubber shock absorber has large damping but high frequency.
Function of the suspended rubber shock absorber:
When the suspended rubber shock absorber receives a large impact, it can automatically limit the maintenance, and at the same time, it can have a strong resistance to the resonance peak. The self vibration energy caused by transient impact response, transient excessive working conditions and other conditions dissipates quickly, and the equipment will not show any shaking.
Hanging rubber shock absorber This product has quite obvious vibration isolation effect in a wide range of interference frequencies, and can be used for vibration isolation of various land and marine mechanical equipment, such as diesel engines, fans, water pumps, air compressors, air conditioners, fine instruments and meters and other small and medium-sized mechanical equipment. Good vibration isolation effect can be obtained by using the vibration isolator for mechanical equipment with a degree of disturbance.
The function of pipeline elastic bracket shock absorber: it has significant effects on vibration and noise reduction of mechanical equipment and noise transmission of pipeline system, further eliminates the impact of sound bridge on structural buildings, and is a kind of vibration reduction measure that cannot be ignored.
It can be said that the suspended rubber shock absorber has both advantages and disadvantages compared with the suspended spring shock absorber. The two can only be said to have their own characteristics, so they will be different in use. If the suspended spring shock absorber is used for high amplitude equipment, it is best to use the suspended rubber shock absorber for high frequency equipment.

Based on years of operation experience, five golden guidelines are summarized for the layout design of bellows compensator:
4.1 Only one bellows compensator is set between any two adjacent fixed supports.
4.2 Various fixed supports shall have sufficient strength and rigidity.
4.3 During installation, it is not allowed to forcibly adjust the deviation of pipeline device by the deformation of bellows compensator.
4.4 The diameter of any two adjacent fixed points shall be the same and in a straight line. The spacing between the first guide, the second guide and the third guide of the compensator shall be reasonably arranged. 4.5 The flow direction of the medium in the process of the device shall meet the requirements of the manufacturer, and the pre stretching shall be stopped correctly to reduce the elastic thrust of the bellows compensator on the fixed support. The pre stretching amount is usually 50% of the thermal compensation amount, The compensator manufacturer shall pre stretch it before leaving the factory. Of course, compared with other compensators, the elastic force of bellows deformation and the thrust of blind plate formed by internal pressure are very large. After calculation, the thrust of a DN200 heavy load fixed point in hot state is about 13 tons, and the comprehensive axial thrust of cold water pressure test is 16 tons. If it is an overhead fixed pier, its root size is 3 m × 2.5 m × 0.8 m larger; However, the bellows compensator is used on the directly buried steam pipeline. Although the thrust received by the fixed point is also 16 tons, it has a proprietary internal fixed support product. The strength and stiffness of the external protective casing are very large, and it is directly buried below 0.8m depth. The soil itself exerts a certain pressure on the steel casing, and the soil itself becomes the huge foundation of the directly buried steam pipeline. The arrangement of bellows compensator in the directly buried steam pipeline is the same as that in the overhead pipeline, but also follows five golden guidelines, which is more stringent than the overhead arrangement in a certain level.
With the long-term implementation of the national energy conservation and emission reduction policy, the direct burial of steam in urban heat supply network will become the main laying method of urban heat supply network, and the bellows compensator will become the main thermal compensation method of urban direct burial heat supply network. Therefore, the correct layout of bellows compensator has become the key to ensure the design quality and safe operation of urban heat supply network.
